2、同步型
同步型交流伺服電動機雖較感應電動機復雜,但比直流電動機簡單。它的定子與感應電動機一樣,都在定子上裝有對稱三相繞組。而轉(zhuǎn)子卻不同,按不同的轉(zhuǎn)子結構又分電磁式及非電磁式兩大類。非電磁式又分為磁滯式、永磁式和反應式多種。其中磁滯式和反應式同步電動機存在效率低、功率因數(shù)較差、制造容量不大等缺點。數(shù)控機床中多用永磁式同步電動機。與電磁式相比,永磁式優(yōu)點是結構簡單、運行可靠、效率較高;缺點是體積大、啟動特性欠佳。但永磁式同步電動機采用高剩磁感應,高矯頑力的稀土類磁鐵后,可比直流電動外形尺寸約小1/2,質(zhì)量減輕60﹪,轉(zhuǎn)子慣量減到直流電動機的1/5。它與異步電動機相比,由于采用了永磁鐵勵磁,消除了勵磁損耗及有關的雜散損耗,所以效率高。又因為沒有電磁式同步電動機所需的集電環(huán)和電刷等,其機械可靠性與感應(異步)電動機相同,而功率因數(shù)卻大大高于異步電動機,從而使永磁同步電動機的體積比異步電動機小些。這是因為在低速時,感應(異步)電動機由于功率因數(shù)低,輸出同樣的有功功率時,它的視在功率卻要大得多,而電動機主要尺寸是據(jù)視在功率而定的。

3、減速器附件
為了保證減速器的正常工作,除了對齒輪、軸、軸承組合和箱體的結構設計給予足夠的重視外,還應考慮到為減速器潤滑油池注油、排油、檢查油面高度、加工及拆裝檢修時箱蓋與箱座的定位、吊裝等輔助零件和部件的合理選擇和設計。
1)檢查孔為檢查傳動零件的嚙合情況,并向箱內(nèi)注入潤滑油,應在箱體的適當位置設置檢查孔。檢查孔設在上箱蓋頂部能直接觀察到齒輪嚙合部位處。平時,檢查孔的蓋板用螺釘固定在箱蓋上。
2)通氣器減速器工作時,箱體內(nèi)溫度升高,氣體膨脹,壓力增大,為使箱內(nèi)熱脹空氣能自由排出,以保持箱內(nèi)外壓力平衡,不致使?jié)櫥脱胤窒涿婊蜉S伸密封件等其他縫隙滲漏,通常在箱體頂部裝設通氣器。

不同溫度環(huán)境下使用鋼卷尺時,應通過線膨脹公式將測量值換算成2℃的值。3m鋼卷尺,在溫度為35℃環(huán)境中使用,它的線膨脹值L以下式計算:L=La(t-to)=3×13×11.5×1ˉ6(35-2)=5.18(mm)式中L—鋼卷尺標稱長度,mm;a—線脹系數(shù),11.5×1ˉ6℃-1;t—測量時溫度(35℃);to—標準溫度(2℃);如果此尺修正值為-1.8mm,那么3m的實際值應為3+5.18-1.8=33.38mm。

一般采用礦物油作為工作介質(zhì),相對運動面可自行潤滑,使用壽命長。很容易實現(xiàn)直線運動。很容易實現(xiàn)機器的自動化,當采用電液聯(lián)合控制后,不僅可實現(xiàn)更高程度的自動控制過程,而且可以實現(xiàn)遙控。液壓的缺點由于流體流動的阻力和泄露較大,所以效率較低。如果處理不當,泄露不僅污染場地,而且還可能引起火災和事故。由于工作性能易受到溫度變化的影響,因此不宜在很高或很低的溫度條件下工作。液壓元件的制造精度要求較高,因而價格較貴。
